He was at the police station yesterday.（改为一般疑问句）

Question

如题所述

Answer 1

Was
he
at
the
police
station
yesterday?
一般疑问句是用yes和no回答的,改法：将陈述句中的be动词，情态动词（can,may,should等）或助动词（do,does,did,have,has等）提前。如：
she
is
a
teacher改为：is
she
a
teacher?
she
can
sing.
改为：can
she
sing?
she
likes
apples.改为：Does
she
like
apples?
特殊疑问句改法（一般以对划线部分提问的形式出现）：
1.特殊疑问词+一般疑问句（去掉划线答案）例如：she
likes
apples改为：what
does
she
like?
2.如果提问主语，将主语用特殊疑问词替掉，后面句子不变。如Mary
is
beautifu.改为：who
is
beautiful?

Answer 2

1)
Was
he
at
the
police
station
yesterday?
一般来说改疑问句分两种情况：
1）一般疑问句
有be动词的，将be动词提到句首。没有be动词的，用助动词来提问，助动词也在句首。
eg
.
I
am
a
student.
Are
you
a
student?
I
like
apples.
Do
you
like
apples?
2）特殊疑问句
特殊疑问句要用疑问词（比如：what，when，how等）来提问。有be动词的句子：”疑问词+be动词
来提问“，没有be动词的：”疑问词+助动词“来提问。
eg.
My
name
is
Mike.
What's
your
name?
I
bought
it
at
the
supermarket.
Where
did
you
buy
it?

station
